Description:

1. material is the basic influencing factor of the hot wound compression spring,we choose alloy steel 60Si2Mn which is common used and verified,60Si2Mn is widely used Si-Mn alloy steel with high strength,elasticity and harden ability,alloy steel 60Si2Mn is suitable for production of working temperature below 250 degree non-corrosive medium heat and spring bear alternating load and important roll of large springs,also automotive suspension systems under high stress and the like.

2. manufacturing process is very important and it effect quality of hot wound spring absolutely.

3. for surface treatment, we add process of shot peening which a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals and composites,with this process,less material is removed and less dust created.

Application:

this hot wound compression spring used in cone crusher,we are spring supplier of GuangZhou Leimeng Machinery Equipment Co.,Ltd who is specialized in the development and manufacture of large-scale crushing and screening equipment (crusher, cone crusher, impact crusher, jaw crusher), a professional mining equipment and provide technical advice of the modern High-tech enterprise group.

Competitive Advantage:

1. comprehensive springs,spring wire diameter 0.08-60mm

2. easy communication and respond quickly

3. strict quality controlling to build a dazzling brand in the spring world
